I received an e-mail from a member of the "Apple Worldwide Recruiting" team, who was partnered with our university. We set up a phone-interview date and time.

I failed the first phone interview, so I am unsure of how the whole hiring process goes. However, here are some details of my experience.

It was right to the point about basic electronic theory, as well as trying to understand my technical standpoint. I think I unfortunately spent too much time thinking about how I'd answer non-technical questions, such as "Why do you want to work here?" and "What are you looking to get out of this experience?" The interviewer dug deep into some of my side projects that I listed on my resume and asked questions I hadn't thought of before. The interviewer was incredibly bright.

Overall, the interview was all technical.

I've unfortunately forgotten the exact details of the question. However, if you are an EE focused generally in the hardware realm, make sure to understand all your basic op-amp theory.

Know your equations, configurations, and how basic circuit theory works.
